HORS ESHOE-CALK.

SPECIFICATION forming part of Letters Patent N0. 605,766, dated J' une 14, 1898. Applicatiorlled February 26, 1898. Serial No. 671,750. (No model.)

To @ZZ whom it may concern,.-

Be it known thatv I, RICHARD WHITAKER,

a citizen of the United States,` residing at New Brunswick, in` the county, of. Middlesex and.

St-ate of New Jersey, have invented certain new and usefull Improvements in Horseshoe-v shoe-calks; and the improvement consists in the novel construction of the calk in connection with simple means for securing the same to horseshoes, Whether said shoes `are unattached or attached to a horses hoof. Its objects are to obtain simple, durable, and inexpensive calks. I attain these objects by the construction illustrated in the accompanying drawings, in whichj Figure l represents, partly `in side view and partly in section, ahorse'shoe showing in transverse section ione heel-calk and a toecalk constructed in accordance with my invention. Fig. 2 is a bottom view of a cylindrical shell-call; as shown on one heel of the shoe in` Fig. l, but Without its fasteningscrew. Fig. 3 is a bottom view of a hexagonal shell-calli. Fig. 4 is a perspective view of the screw-bolt for said hexagonal calk. Fig. 5 is a bottom perspective view of a square shell-calk. Fig. 6 is a` bottom perspective view of an octagonal shell-calli. Fi-g. 7 is a top perspective view of a cylindrical shellcalk as in Fig. 2, but provided with a short polygonal boss or head. v

In said drawings, Arepresents a horseshoe of any suitable and well-known form,to which is shown secured to one of the heels a cylindrical or tubular calk, preferably made of sheet-steel in the form of a shell B, having an inwardly-projecting collar b on its upper end. Said calk is secured to the shoe by means of a screw C, having a comparatively stout body and a thin head, having a slot therein adapted to receive the end of a screwdriver or other suitabletool to rotate it.

In Fig. 3 is shown a hexagonal tubular shell-calli D. (Shown secured to the toe of the shoe in Fig. l.) Said calk is also provided with an inwardly-projecting collar d on its upper end yandv is secured to the shoe by means` of a bolt E, having a comparatively thin polygonal head e, made with the same number of faces as the calk and wholly surrounded by the walls of said calk.

The shell-calli F shown in Fig. 5 and the shell-calk G in Fig. 6 are modifications of the calli shown in Fig. 3 simply in the number of faces and are to be secured to the shoe with bolts having preferably polygonal heads with corresponding number of faces.

The shell-call; B2 shown in Fig. 7 is a modification ofthe cylindrical calk B. It is provided with a thinpolygonal head b2, intended to be received in a similar shallow polygonal depression in the shoe to prevent its rotation if ascrew made with a cylindrical head is used as a fastener. Thepolygonal calks D F G may also with advantage be provided with a thin polygonal head, particularly if a screw made with a cylindrical head is used to fasten them to a horseshoe. If a bolt having a tapped hole ct in the shoe and the bolt and call; rotated together, first by the operators hand and then with a wrench, until it obtains a firm hold against the bottom of the shoe.

As the calks are made with an endless periphery from top to bottom and a lat annular bottom edge h there is no danger of a horse injuring itself with the calks while wearing them.

Having now fully described my invention, I -claiml. A removable horseshoe-calli consisting of a polygonal tubular shell having an inwardly-projecting collar on its upper end, in combination with a polygonal-headed screw having the tlat projecting part of its head adjacent to its body bearing against said collar and its faces in engagement with the polygonal inner sides of the calli, substantiallyT as described.

2. A horseshoe-calk lconsisting of a tubular shell having an inwardly-proj ecting collar on its upper end and a hollow polygonal head on top of said collar, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

RICHARD VHITAKER.
